Abstract
In this study, about 80 Kentucky bluegrass (Poa pratensis L.) ecotypes native to Korea were collected annually to analyze their morphology and growth characteristics from 1995 to 2007. Kentucky bluegrass ecotypes with superior characteristics of 'Pureundle' (Trial No. : P38), 'Sewon' (P77), 'Inje' (00034), 'Donggang' (00052), 'Hwasun' (01001), 'Pyengchang' (01071), 'Kongju' (02006), 'Chungsong' (02077), and 'Kumsan' (03005) and three foreign cultivars were transplanted to flowerpots in May 8, 2006 in order to analyze the blooming and morphological characteristics. Out of the selected superior ecotyes, six were collected on the roadsides, two were collected around paddy or dry fields, and one was collected at riverside. Length of 1st internode of 'Chungsong' was the longest (30.7cm), that of 'Pyengchang' was the shortest (12.8cm), and ecotypes showed variation in length. The 1st angle of branches of 'Donggang' was the narrowest (
